Aqueous jet composition

In various fluorescent dyes, C.I. solvent yellow 16 0:1, C.I. disperse yellow 82 and C.I. disperse yellow 184 have fluorescence strong The features such as excellent is spent, on the other hand, is had the following problems.That is, above-mentioned fluorescent dye is being used as existing aqueous jet composition Constituent when, it is difficult to have both aqueous jet composition storage stability and the nose filter caused by dry or The difficult generation property of the blocking of nozzle.

Therefore, the present inventor is contaminated with applying flexibly excellent characteristic possessed by above-mentioned fluorescent dye and having both comprising the fluorescence The difficult of the blocking of the storage stability of the aqueous jet composition of material and the nose filter caused by dry or nozzle sends out It is having made intensive studies as a result, completing the present invention for the purpose of natural disposition.

That is, aqueous jet composition of the invention is characterized in that, contain: selected from by C.I. solvent yellow 16 0:1, C.I. At least two dye components in specific weld group that disperse yellow 82 and C.I. disperse yellow 184 are constituted；Disperse with sulphonic acids Agent, the sulphonic acids dispersing agent are the dispersing agent of at least one of the salt with sulfo group and sulfo group chemical structure.

By such composition, it is capable of providing a kind of aqueous jet composition, which is playing While excellent characteristic possessed by the dye component (specific weld), has both storage stability and caused by drying Nose filter or the difficult of blocking of nozzle property occurs.

It is considered that obtaining such excellent results is because of by using the salt with hydrophily high sulfo group and sulfo group At least one of chemical structure sulphonic acids dispersing agent, the aqueous jet composition in nozzle etc. can be effectively prevented It is dry, although and by containing with the coumarin skeleton as common chemical structure, the chemistry of compound entirety At least two different specific welds of structure are (selected from by C.I. solvent yellow 16 0:1, C.I. disperse yellow 82 and C.I. disperse yellow At least two dye components in the 184 specific weld groups constituted), with phase the case where only containing a kind of specific weld Than the precipitation of the crystallization of the crystallization of specific weld, especially predefined size or more can be effectively prevented.

It is considered that can prevent the crystallization of specific weld is due to following reason.That is, as described above, constituting The specific weld of specific weld group has coumarin skeleton as common chemical structure, therefore deposits when stored etc. The case where with multiple molecules close in stable conditionization, but the chemical structure of the compound entirety due to each specific weld It is mutually different, therefore prevent excessive specific weld molecule from agglomerating.Therefore, even if specific weld molecule occurs Agglutination, agglutination body is also not easy to grow into coarse crystallization, with minimum agglutination body and being used in combination with sulphonic acids dispersing agent Dispersity or the agglutination body is kept to form stable to occur decompose, spread again again.

In this regard, in the case where being unsatisfactory for above-mentioned condition, the result that cannot be satisfied with.

For example, a kind of specific weld is used only, not and with two or more specific welds in the case where, water The storage stability of property ink-jet composition is low, in aqueous jet with being easy to produce foreign matter in composition when preservation.

In addition, in the case where replacing specific weld using other fluorescent dyes, specific weld being not used, In In the record portion formed using aqueous jet composition, it is difficult to obtain sufficient fluorescence intensity.It should be noted that this explanation In book, " record portion " is other than the position for being imparted the recording medium of aqueous jet composition using ink-jet method, also wrapped It includes and has transferred aqueous jet combination in the case where the thermal transfers impact systems such as aqueous jet composition application distillation printing and dyeing The concept at the position of the constituent of object.

In addition, in the case where unused sulphonic acids dispersing agent, it is difficult to so that the dispersion in aqueous jet composition is steady It is qualitative sufficiently excellent, in aqueous jet with being easy to produce foreign matter in composition when preservation.

In addition, instead of sulphonic acids dispersing agent, using such as point with the functional group higher than sulfo group of hydrophobicity carboxyl In the case where the dispersing agent in addition to sulphonic acids dispersing agent such as powder, for example, when nozzle dry running, long-term place etc. will make in this way When being placed in the state for being easy drying for the ink for inking of aqueous jet composition, the solid component of aqueous jet composition It is particularly easy to be precipitated, is easy to happen the ejection of the aqueous jet composition as caused by blocking of nose filter or nozzle etc. not It is good.

It should be noted that in this specification, the aqueous jet ink sheet that composition is in addition to being sprayed using ink-jet method Other than body, further include the concept for being used to prepare the stoste of the ink.In other words, aqueous jet composition of the invention can be straight The ejection for being used in ink-jet method progress is connect, the ejection of ink-jet method progress can also be used in after the processing such as dilution.
